Upgrade to .NET 10 and Aspire 13 #2036

Copilot · 2025-11-12T17:52:53Z

Upgrades project from .NET 9 to .NET 10 and Aspire 9.5 to 13.0.

SDK & Runtime

Updated to .NET 10.0.100 SDK and net10.0 TFM
Aspire.AppHost.Sdk: Correctly set to version 9.5.2 (SDK version is separate from package versions)
Updated Docker base images and installation scripts
Updated GitHub Actions workflows
Updated VSCode launch.json debug paths from net9.0 to net10.0

Aspire 13 Breaking Changes

Replaced Aspire.Hosting.NodeJs → Aspire.Hosting.JavaScript
Replaced AddNpmApp() → AddJavaScriptApp() (supports npm/yarn/pnpm auto-detection)
Replaced WithEndpoint() → WithHttpEndpoint()
KibanaConfigWriterHook: Temporarily disabled with conditional compilation (#if FALSE) and marked with TODO for migration to Aspire 13's IDistributedApplicationEventingSubscriber eventing model

.NET 10 API Changes

ForwardedHeadersOptions.KnownNetworks → KnownIPNetworks
Removed package references now included in framework:
- System.Net.Http, System.Text.RegularExpressions, System.Text.Encodings.Web
- Microsoft.Extensions.Diagnostics.HealthChecks (now implicit in ASP.NET Core)

Package Updates

All Microsoft.Extensions.* and Microsoft.AspNetCore.* packages: 9.0.10 → 10.0.0
All Aspire packages: 9.5.2 → 13.0.0

Test Fixes

Updated AppWebHostFactory to use fully qualified Exceptionless.Web.Program class reference for .NET 10 compatibility

Known Issues

KibanaConfigWriterHook requires migration to Aspire 13's new eventing model and is currently disabled. See TODO comments in the code for migration guide references.

Example Changes

// Before (Aspire 9.5)
builder.AddNpmApp("Web", "../../src/Exceptionless.Web/ClientApp", "dev")
    .WithEndpoint(port: 5173, targetPort: 5173, scheme: "http", env: "PORT");

// After (Aspire 13)
builder.AddJavaScriptApp("Web", "../../src/Exceptionless.Web/ClientApp", "dev")
    .WithHttpEndpoint(port: 5173, env: "PORT");

@copilot fix the kibana todo, remove the upgrade notes file and also look for other things to upgrade like the vscode tasks/launch might have debug paths to a net9 folder.

@copilot fix the kibana todo, remove the upgrade notes file and also look for other things to upgrade like the vscode tasks/launch might have debug paths to a net9 folder.

Fixed in commit a66d929:

Kibana TODO fixed: Implemented using Aspire 13's EnvironmentCallbackAnnotation approach instead of the deprecated lifecycle hooks. The new ConfigureElasticsearchHosts extension method properly configures the ELASTICSEARCH_HOSTS environment variable for Kibana.
Upgrade notes removed: Deleted UPGRADE_NOTES.md
VSCode launch.json updated: Changed all debug paths from net9.0 to net10.0 for Aspire, Web, and Job configurations.

Build verified successfully. ✅

Fixed in commit c19bb00:

Corrected Aspire.AppHost.Sdk version to 9.5.2

Added comprehensive TODO comments with references to Aspire 13 migration guide
Disabled KibanaConfigWriterHook with conditional compilation until proper migration

Updates various package dependencies across multiple projects. This includes updates to FluentValidation, Serilog.Sinks.Console, OpenTelemetry, Swashbuckle.AspNetCore.Newtonsoft, FluentRest.NewtonsoftJson, and Microsoft.NET.Test.Sdk. Also adds System.Net.Http and System.Text.RegularExpressions to resolve vulnerability warnings related to transitive dependencies.

We may want to consider doing all the work to drop it, but was looking for a quick upgrade: https://learn.microsoft.com/en-us/aspnet/core/fundamentals/openapi/overview?view=aspnetcore-10.0

Adds a test case to verify event serialization, including environment and request information, ensuring correct snake_case serialization of the JSON output. Also adds OpenAPI spec.

Updates project dependencies to the latest versions, including Aspire, FluentValidation, MaxMind.GeoIP2, Serilog, and OpenTelemetry, to leverage the newest features, improvements, and bug fixes.

        return result;
    }
+
+    [Fact]


The new test PostEvent_WithEnvironmentAndRequestInfo_ReturnsCorrectSnakeCaseSerialization lacks documentation comments explaining its purpose. Consider adding a summary comment explaining that this test verifies the snake_case serialization format for event data with environment and request information, which is important for API compatibility.

src/Exceptionless.Web/Utility/RequestBodyOperationFilter.cs

+            operation.RequestBody.Content!.Add(contentType, new OpenApiMediaType
            {
-                Schema = new OpenApiSchema { Type = "string", Example = new OpenApiString(String.Empty) }
+                Schema = new OpenApiSchema { Type = JsonSchemaType.String, Example = JsonValue.Create(String.Empty) }


The Schema property initialization uses JsonSchemaType.String which is correct for .NET 10, but the Example property uses JsonValue.Create(String.Empty). Consider using new JsonNodeExtension(JsonValue.Create(String.Empty)) to properly wrap it as an IOpenApiExtension, as done in the XEnumNamesSchemaFilter.

Adds webhook subscription and unsubscription endpoints. Enhances stack management by allowing marking stacks as fixed and adding links using JSON documents. Also includes minor fixes and improvements, such as using options objects directly in Startup.cs and correcting a parameter description in the ProjectController.
